IMPROVEMENT IN GOVERNORS.

Spedfiration forming part of Letters Patent No. 144,205, dated November4, 1873; application filed October 17, 1873.

To all whom it may concern:

Be it known that I, JOHN E. HUGOU, of Richmond, Wayne county, Indiana,have invented certain Improvements in Governors for .Steam-Engines, ofwhich the following is a specification My invention relates to animprovement in governors for steam-engines, wherein I use a rotary valveor valves fitted into a cylindrical valve-seat, said seat being inclosedwithin a chamber. The rotary valve has arms H H, to which thepacking-plates E E are attached, as hereinafter described.

Figure 1 is a vertical section of the outer casing, inclosing thechamber B also showing a cross-section of the valve and valve-seat. Fig.2 is a section of the valve, showing the manner of attaching thepacking-plates.

A is the outer casing, inclosing the chamber B and cylindrical valveseat O. I The packingplates E E cover the ports G G, and H H are thearms of the valve, to which the packingplates are attached by means ofthe notches I I passing through the plate, as shown in Fig. 2. F is arecess in the arm, into which the packing-plate is placed. The arm andplate may be made solid or in one piece, and thus form a balance-valve;or it may be constructed as shown, and serve the purpose of abutterfly-valve. The steam presses the packing-plate tightly against thevalve-seat O. G G are the ports.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

The combination of the cylindrical valveseat 0, placed in the chamber B,the valve K, having the arms H, and packing-platesE, with the ports G,all arranged and opcratln g substantially as described.
